Background This study investigates factors associated with electronic cigarette (e-cigarette) use and secondhand exposure in vehicles among US youth and young adults. Methods Data were collected from an online panel survey of individuals (N=3482, aged 15–25 years) from July to December 2024. Analyses included those who reported using any tobacco product in the past 30 days and answered items measuring exposure to (N=2600) and/or use of e-cigarettes in vehicles (N=2366). Logistic regression models assessed predictors of e-cigarette use and exposure in vehicles, including demographic, psychosocial and tobacco use characteristics. Results Among all participants, 67.1% reported e-cigarette use in the past 30 days. Of those reporting current e-cigarette use (N=2336), 60.6% reported using their e-cigarette/vape while travelling by car in the past 30 days. Of those who answered the question measuring exposure to e-cigarette use in vehicles (N=2600), 69.3% reported being in a vehicle where someone was using e-cigarettes. Higher nicotine dependence and residence in small metro and non-metro areas were associated with greater odds of using e-cigarettes in vehicles. Just meeting basic expenses or meeting needs with a little left, household tobacco use and residence in small metro areas were associated with greater odds of secondhand e-cigarette exposure. Discussion Public health interventions should place a strong focus on education and increasing public awareness of the health consequences of e-cigarette use in vehicles to protect bystanders from secondhand e-cigarette exposure.

Background: Cardiac biomarkers are recognized as potential indicators for brain function, emotion regulation, and psychiatric risk. While research in adults has suggested associations between cardiac variables of autonomic function and neural changes, little is known about these relationships in children and young adults with psychiatric conditions. This systematic review aimed to examine the evidence linking cardiac biomarkers with structural, functional, and connectivity-based brain changes in this population. Methods: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Multiple databases were searched for studies examining associations between any cardiac biomarker and neuroimaging findings in individuals under 21 years old with psychiatric diagnoses. After screening and full-text review, 11 eligible studies were included. Results: The included studies investigating a range of psychiatric conditions and cardiac biomarkers were associated with brain changes across three domains: structure, connectivity, and neural responses. Associations were most consistent between higher vagal tone and structural and functional integrity of emotion-regulating regions such as the prefrontal cortex, amygdala, and insula. However, findings were heterogeneous and potentially moderated by symptom severity or environmental stressors. Conclusions: This review supports the potential of cardiac biomarkers, particularly high-frequency heart rate variability and root mean square of the successive differences, as proxies of brain changes in youth with psychiatric disorders. While promising, current evidence is too limited and variable for clinical applications. Future research should prioritize large-scale, longitudinal studies using harmonized protocols and wearable technologies to validate these indices as translational tools in child and adolescent psychiatry.

Background: Polydactyly surgery rates and trends are poorly characterized. The purpose of this study was to characterize national pediatric polydactyly management by examining operative and procedural trends over time, evaluating timing of treatment, identifying factors associated with interventions, and comparing costs and complications. Methods: We used the PearlDiver national administrative claims database to identify pediatric patients aged 18 and under with a diagnosis of polydactyly (2010-2023). We analyzed patients who received procedures coded as surgical correction or suture ligation, then characterized rates and factors associated with each intervention, and investigated postoperative complication rates. Results: Of 42 543 polydactyly patients, 3880 patients (9.1%) underwent surgery, and 5612 patients (13.2%) underwent procedures coded as suture ligation. Over the past decade, the incidence of polydactyly diagnosis and surgery has decreased, while rates of procedures coded as suture ligation have not changed significantly. In 2010, 12.0% of patients underwent surgery, compared to 7.3% in 2020. Patients of ages 1 to 2 years comprised the greatest proportion of the population who underwent surgical operations at 1729 patients (36.0%), and patients of ages 0 to 1 year comprised the greatest proportion of the population who underwent suture ligations at 3327 patients (51.0%) ( P < .001). Younger age at diagnosis and higher comorbidity index were associated with a greater likelihood of surgery, while greater mean family income was associated with a lower likelihood. Among treatment categories, surgery was associated with greater 1-year and total payer-reimbursed costs ( P < .05). Conclusions: We observed a declining incidence of pediatric polydactyly and polydactyly surgery. These findings may inform future guideline development and discourse for pediatric hand care.

This study aims to evaluate the implementation of the uterine sliding sign in routine pelvic ultrasound examinations for improving the diagnosis of deep endometriosis. A retrospective analysis was conducted at Mayo Clinic’s Florida and Arizona campuses, including 200 premenopausal and perimenopausal women with chronic pelvic pain, infertility, or suspected endometriosis. Sonographers performed a uterine sliding maneuver during transvaginal ultrasound, and the acquisition times were recorded. Sonographer experience and the time required to perform the sliding sign were analyzed using Microsoft Excel. The median acquisition time for the uterine sliding sign was 26 seconds, with no statistically significant difference based on sonographer experience. The addition of this maneuver extended the ultrasound examination by <1 minute on average, regardless of sonographer experience level. Incorporating the uterine sliding sign into routine pelvic ultrasound protocols is a quick and efficient method that enhances the detection of deep endometriosis, potentially reducing the significant diagnostic delay associated with endometriosis. This study supports the feasibility and minimal time impact of implementing the Society of Radiologists in Ultrasound (SRU) recommendations for augmented pelvic ultrasound in clinical practice.

Common sex chromosome aneuploidies (SCAs) often present with cognitive and cardiovascular dysfunction in humans. To address SCA effects on gene expression and DNA methylation in relevant cell types, we differentiated neural precursor cells (NPCs) and cardiomyocytes (CMs) from human induced pluripotent stem cells (hiPSCs) with different numbers of sex chromosomes, including isogenic and independent lines. As expected, the expression of genes that escape X inactivation (escapees) mostly increases with the number of inactive X chromosomes (Xi). However, allelic analysis shows dampening of escapees specifically on the Xi in XXY compared to XX in both NPCs and CMs, revealing a novel type of dosage compensation in SCA. In contrast, Y-linked gene expression is higher in XXY versus XY NPCs, but the opposite is observed in CMs. This may explain the greater number of differentially expressed autosomal genes in NPCs versus CMs with an added Y chromosome, while effects of added X chromosomes are similar between cell types. Concordantly, changes in autosomal DNA methylation are mainly driven by the presence of a Y chromosome. These findings highlight the cell-type specificity of sex-linked and autosomal gene regulation in SCA conditions.

Importance Young adults (YAs; ages 18-39 years) diagnosed with cancer face unique psychosocial challenges, including high distress and poor health-related quality of life (HRQOL). There are few efficacious interventions tailored to their needs. Objective To evaluate the efficacy of Bright IDEAS-YA, a problem-solving skills training intervention tailored for YAs, in reducing distress and improving HRQOL. Design, Setting, and Participants This randomized clinical trial was conducted at 3 academic medical centers and enrolled participants between February 2021 and March 2024. Eligible participants were aged 18 to 39 years, within 4 months of a first cancer diagnosis, and undergoing systemic therapy. Participants completed surveys at baseline and 3, 6, 12, and 24 months. Intervention Bright IDEAS-YA is a 6-session, one-on-one intervention that teaches a structured approach to problem-solving. Enhanced usual care (EUC) included standard psychosocial care plus a list of adolescent and YA resources. Main Outcomes and Measures Primary outcomes were depression and anxiety (Patient-Reported Outcomes Measurement Information System Short Forms) and HRQOL (Functional Assessment of Cancer Therapy-General) at 6 months. Problem-solving ability (Social Problem-Solving Inventory-Revised Short Form) was examined as a mediator. Analyses used linear mixed effects models and mediation analysis. Results Of the 1128 YAs screened, 344 YAs (median [IQR] age, 31.27 [25.78-36.38] years; 251 female [62.5%]) enrolled, with 171 allocated to intervention and 173 allocated to control. Overall, 296 YAs (86.0%) and 280 YAs (81.4%) completed 3- and 6-month surveys, respectively. At 6 months, the intervention group showed significantly greater improvements than EUC in depression (effect size estimate, −3.23 points; 95% CI, −4.93 to −1.53 points; P &amp;lt; .001), anxiety (effect size estimate,−2.43 points; 95% CI, −4.05 to −0.81 points; P = .003), and HRQOL (effect size estimate, 3.40 points; 95% CI, 0.34 to 6.45 points; P = .03). These changes were clinically meaningful. Mediation analyses showed that improvements in depression and anxiety were partially due to increased problem-solving ability, particularly reductions in negative problem orientation. Sex and education were moderators of treatment effect, with the treatment effect on anxiety being greater for males (effect size estimate, −5.29 points; 95% CI, −7.97 to −2.60 points) and the treatment effect on anxiety (effect size estimate, −6.94 points; 95% CI, −10.50 to −3.43 points) and depression (effect size estimate, −7.47 points; 95% CI, −11.20 to −3.74 points; P &amp;lt; .001) being greater for those with lower education. Conclusions and Relevance In this randomized clinical trial of Bright IDEAS-YA, intervention participants had significantly reduced distress and improved HRQOL relative to control. These findings suggest that Bright IDEAS-YA may be offered as supportive care for YAs with cancer to improve psychosocial outcomes. Trial Registration ClinicalTrials.gov Identifier: NCT04585269
